Add extradata to the beginning of the filtered packets.
+@table @option
+@item freq
The additional argument specifies which packets should be filtered.
It accepts the values:
@table @samp
-@item a
-add extradata to all key packets, but only if @var{local_header} is
-set in the @option{flags2} codec context field
-
@item k
+@item keyframe
add extradata to all key packets
@item e
+@item all
add extradata to all packets
@end table
+@end table
-If not specified it is assumed @samp{k}.
+If not specified it is assumed @samp{e}.
For example the following @command{ffmpeg} command forces a global
header (thus disabling individual packet headers) in the H.264 packets
ffmpeg -i INPUT -map 0 -flags:v +global_header -c:v libx264 -bsf:v dump_extra out.ts
@end example
+@section eac3_core
+
+Extract the core from a E-AC-3 stream, dropping extra channels.
+
@section extract_extradata
Extract the in-band extradata.
bitstream after extraction.
@end table
+@section filter_units
+
+Remove units with types in or not in a given set from the stream.
+
+@table @option
+@item pass_types
+List of unit types or ranges of unit types to pass through while removing
+all others. This is specified as a '|'-separated list of unit type values
+or ranges of values with '-'.
+
+@item remove_types
+Identical to @option{pass_types}, except the units in the given set
+removed and all others passed through.
+@end table
+
+Extradata is unchanged by this transformation, but note that if the stream
+contains inline parameter sets then the output may be unusable if they are
+removed.
+
+For example, to remove all non-VCL NAL units from an H.264 stream:
+@example
+ffmpeg -i INPUT -c:v copy -bsf:v 'filter_units=pass_types=1-5' OUTPUT
+@end example
+
+To remove all AUDs, SEI and filler from an H.265 stream:
+@example
+ffmpeg -i INPUT -c:v copy -bsf:v 'filter_units=remove_types=35|38-40' OUTPUT
+@end example
+
+@section hapqa_extract
+
+Extract Rgb or Alpha part of an HAPQA file, without recompression, in order to create an HAPQ or an HAPAlphaOnly file.
+
+@table @option
+@item texture
+Specifies the texture to keep.
+
+@table @option
+@item color
+@item alpha
+@end table
+
+@end table
+
+Convert HAPQA to HAPQ
+@example
+ffmpeg -i hapqa_inputfile.mov -c copy -bsf:v hapqa_extract=texture=color -tag:v HapY -metadata:s:v:0 encoder="HAPQ" hapq_file.mov
+@end example
+
+Convert HAPQA to HAPAlphaOnly
+@example
+ffmpeg -i hapqa_inputfile.mov -c copy -bsf:v hapqa_extract=texture=alpha -tag:v HapA -metadata:s:v:0 encoder="HAPAlpha Only" hapalphaonly_file.mov
+@end example
+
@section h264_metadata
Modify metadata embedded in an H.264 stream.
For example, @samp{086f3693-b7b3-4f2c-9653-21492feee5b8+hello} will
insert the string ``hello'' associated with the given UUID.
+@item delete_filler
+Deletes both filler NAL units and filler SEI messages.
